–
E
XPOSURE
T
IME
The

ETTING ALARM THRESHOLDS FOR DOSE METER RESULTS
–
A
LARM
The
Alarm
position is active only in the
Dosimeter
function and enables programming the alarm thresholds
for three profiles (
Thresh. P1 (2,3)
).
Thresholds can be set for next measurement results of
the
Dosimeter
in ranges:
<ENT>
DOSE
: 1÷200%;
D_8h
: 1÷200%;
PTC
: 1÷1000;
ULT
: 1÷60s.
If
Off
is selected, the alarm for the measurement result
is switched off.
